That 100 A figure holds steady at every 5 °C increment through 70 °C, so the thermal curve is flat within the operating envelope. The breaking capacity is 440 kA at 240 V, stepping down to 330 kA at 415 V and 440 V, 220 kA at 500 V, and 53 kA at 690 V. For a panel designer, that means this breaker can sit at the service entrance on a high-fault installation and still coordinate downstream without cascading upstream. The ETU350 electronic trip unit gives adjustable N-conductor protection (OFF, 50%, 100%) and an adjustable response time (tr) from 0.5 s to 17 s. That adjustability matters when you're coordinating selectivity with downstream breakers — you can dial in the time band to match the load's inrush without nuisance tripping. The 20,000-cycle mechanical endurance is per the latching count; this is a line-protection breaker, not a switching device for frequent load cycling. No communication module is integrated; this is a standalone line-protection breaker without fieldbus or measurement functions.","metaTitle":"Siemens 3VA2010-8HN42-0AA0 SENTRON MCCB, 100 A, 4-Pole, 440","metaDescription":"Siemens SENTRON 3VA2010-8HN42-0AA0 molded case circuit breaker, 100 A rated continuous current, 4-pole, ETU350 electronic trip, 440 kA at 240 V.
